STRONG ACID EQUIVALENT CONTROL OF PH PROCESSES - AN EXPERIMENTAL-STUDY Academic Article

abstract

• The control of pH is widely recognized as a difficult problem. The strong acid equivalent approach for control of pH processes consists of defining an equivalent control objective, the strong acid equivalent, and using a linear control law in terms of this new control objective. The strong acid equivalent is calculated on-line from pH measurements given a nominal titration curve of the process stream. A laboratory system has been built to implement this method. Experimental results for the hydrochloric acid-sodium hydroxide and acetic acid-sodium hydroxide systems are given. The results demonstrate the performance of the strong acid equivalent control method. 1991, American Chemical Society. All rights reserved.
